Bedika Cloths

Does anyone else have this problem? I feel like I’m always bringing them to the rov to get checked and 99.9% of the time they’re fine.

I just don’t understand why there’s always brown on them when the last 2 years they were basically almost pristine.

Sometimes there’s a lot sometimes a little sometimes I thought they’d fsure say it’s not fine but it is.

Can anyone help me please 🙏🏼

Editing to add: during the Shiva Nekim usually first 1-3 days.
